Title: Shears for cutting metal bar lengths - with reversible measuring belt conveyor and second shears for crop end
Inventor: PEDDINGHAUS CARL ULLRICH DR
IPC: B23D23/00
Filed: 1973-07-19
Abstract: Shears for cutting lengths of steel bars to given sizes, combines an automatic length measurement with a second set of shears to reduce the crop end of the last cut to a minimum. The bar is fed to the shears by a roller table. It is held by pressure rollers in contact with an endless belt, which measures the length a rev counter. When a comparator establishes that the length equals the set value, a control unit stops the belt drive motor. Shears then cut the bar to length. The discharge roller table descends with the upper blade. For the last cut, the belt direction can be reversed and shears are used to cut the minimum length of wasted crop end.

Title: Noise suppressor for stereo FCC systems with stereo-mono switch - integrates filtered stereo differential signals to control cross-talk attenuation
Inventor: SAX HERBERT
IPC: H04B1/16
Filed: 1973-07-28
Abstract: The noise suppressor for stereo FCC systems with stereo-mono switching filters out the differential components in the stereo signal, integrates them, and uses them to control cross-talk attenuation. these integrated signals are also limited and passed to a trigger which controls the stereo-mono indicator. The differential components are removed from the stereo decoder output via a differential amplifier, or a filter, or a matrix decoder. The cross-talk attenuation is controlled via a matrix between both audio channels behind the stereo decoder or, when used, via part of the matrix decoder.

Title: Starting cct. for single-phase async. motors - has protective PTC resistors whose highest temp. triggers supply cct. breaker
Inventor: VILHELM VIND HOLGER
IPC: H02H5/04
Filed: 1973-08-20
Abstract: The starting circuit protects a single-phase asynchronous motor main and starting windings during starting from overload if the rotor fails to rotate. A PTC resistor is connected in series with the starting winding across the supply and its increase in resistance protects the winding during the motor starting phase. When the resistor reaches its highest permissible temperature, it operates a thermally triggered circuit breaker which cuts out the supply to both the main and the starting windings. The PTC resistor consists of a flat disc between two electrodes. The circuit breaker lies in thermal contact with one of these electrodes. The whole circuit is conveniently contained in a single housing.

Title: Desuperheater valve for control of steam conditions - has cooling water injected through atomising nozzle facing valve seat
Inventor: KLIMPFINGER ERWIN ING
IPC: F22G5/12
Filed: 1973-10-19
Abstract: The valve body contains a cylindrical insert which has the valve seat at its top. The valve plug seats on this and has a conical projection into the insert.

Title: Kitchen scales with movable upper and lower housings - has linear scale with indicator band for compact size
Inventor: ZUMSTEEG WILLFRIED DIPL ING
IPC: G01G23/20
Filed: 1974-02-14
Abstract: The scales have a base frame and a weighing frame movable vertically relative ot the main frame, a spring between the two frames and a weight indicator comprising a scale and a measuring gear mechanism which converts the vertical movement of the weighing frame into a rotational movement of an indicating element relative to the scale.

The scales permit rapid and accurate readings for both small and large amounts.
Patent DE-2407523-A1 (DE)
Title: Photosensitive FET transistor amplifier - produced by boron diffusion through windows and layer of incomplete silicon oxide mask
Inventor: KOENIGER MAX DIPL PHYS DR
IPC: H01L31/112
Filed: 1974-02-16
Abstract: A photosensitive amplifier with low- and highly doped zones in a semiconductor crystal is produced by etching windows in the SiO2 coating of a monocrystalline silicon wafer. A subsequent boron diffusion affects the windows and is continued until a slight doping reversal has taken place under the SiO2 coating in the layer near the surface. This produces doping profiles in which space charge regions can reach as far as the surface; the detecting radiation can enter the photosensitive part unimpeded by contacts and the signals produced by the light are amplified in the FET-like structure. The manufacturing costs are extremely low.

This enables the driver to view over a greater field for added safety. The mirror sections are separately adjusted, either manually or by remote control to give adjacent or widely separated fields of view.
